Ryu would be the first Sunday option, but it's uncertain when he'll be ready. He injured the nail on his right big toe Sunday in Australia running into the third base bag. It tore the nail. On Tuesday he saw a podiatrist and said about half of it was cut off.

"They said it looked really good," Ryu said.

He went through pitching motions in the bullpen Wednesday -- but without throwing the ball -- and reported improvement with the toe.

"He felt pretty good in the bullpen," Mattingly said. "We'll see how that goes tomorrow. And that's when we'll make a decision on Sunday. We're a little bit day-to-day with Hyun-Jin."

Whether or not Haren is forced into the nationally televised opener on Sunday, following Monday's off-day, Greinke will start Tuesday. Greinke is coming off a spring calf injury and is first scheduled to start Thursday's exhibition game against the Angels.

Wednesday could see Haren, Maholm or Ryu start. It's the undefeated Dodgers' first three-game series of the season and they're already in serious play-it-by-ear mode.
